More data to suggest no need for protein shakes immediately after workout if you already eat enough protein during the day. From the paper: "The additive effects of resistance-type exercise and protein ingestion on myofibrillar protein synthesis persist for >12 h after exercise and are not modulated by protein consumption during acute post-exercise recovery. This work provides evidence of an extended window of opportunity where pre-sleep protein supplementation can be an effective nutrient timing strategy to optimize skeletal muscle reconditioning."
